FIX/FAST Operators Release
Based on customer feedback, the removal of the operators from CME FX futures channels 11 and 60 in the production environment, previously scheduled for Sunday, June 3, has been postponed to Sunday, July 1. On Sunday, June 3, 2012, these operators will be removed from the streamlined FIX/FAST Eris Exchange channel 190 in the production environment. The new template and updated messages are currently available in New Release and the new template is currently available in Production.

The life cycle of the FIX/FAST protocol, including streamlined FIX/FAST, is rapidly approaching its end as an industry standard in the United States. †The OPRA connected exchanges are eliminating FIX/FAST entirely by the end of this year. Given the increased availability of bandwidth as well as high speed connections such as co-location, compression has become less critical. In the short term, we are removing certain field operators (copy, default, delta and increment) from our data feed. In the longer term, CME Group continues to evaluate a next generation market data protocol.

These operators will be removed from all production FIX/FAST and streamlined FIX/FAST channels on the Market Data Platform by Sunday, November 4, 2012. Detailed schedules for every channel will be published in the CME Globex and Market Data Notices.

New templates will be required for the impacted channels. The new templates are currently available in New Release and Production. CME Group recommends customer systems pull the templates from the CME Group ftp site every week, prior to Sunday startup. More information on template management is available in the Client Systems Wiki.

These changes are currently available on all FIX/FAST channels in the New Release environment.

As a result of this launch, bandwidth utilization over the Market Data Platform will ultimately increase. CME Group is contacting customers who may have over-subscription risk.

†Please note: CME Group is not a member of the Options Pricing Reporting Authority (OPRA).

Changes to Source IPs for the Market Data Platform B Feed for Non-GLink Connections
Effective Sunday, June 17, 2012, CME Group will be changing multicast source IPs for the B feed only for non- GLink connections. If a firewall or network device is configured with the source IP information, please correct your configuration to use the entire range of eligible addresses. Port, multicast addresses, and source IPs for each Market Data Platform channel are available in the config.xml file on the FTP site as outlined in the Core Functionality of the FIX/FAST SDK.

Market data will be broadcast on all CME Group FIX/FAST channels in the production environment for customer testing on Saturday, June 16. Market data will be broadcast from the new B feed source IPs.

8:30 - 9:00 a.m. CT: Connectivity testing

9:00 - 10:00 a.m. CT: FIX/FAST market data replay

As a reminder, CME Group requires that customers configure servers to connect to the Market Data Platform ports and multicast addresses for each desired channel. CME Group does not recommend restricting data flow via the source IPs, as these may change without notice.

If you have any questions or concerns, please contact your Global Account Manager. If you experience any connectivity issues, please contact the CME Global Command Center directly at 312.456.2391.

Green Exchange Product Migration to NYMEX Available in New Release
As previously announced, CME Group anticipates in the near future migrating all GreenX products to a CME Group exchange, delisting them from the Green Exchange and listing them on the NYMEX exchange. The date of this migration is dependent upon receipt of an order from the CFTC permitting such a migration.

These products will use the same Symbol (tag 55) and SecurityGroup (tag 1151) as they do today, however the value in tag 207-SecurityExchange will be updated from GREE to XNYM.

Market data for these products will continue to be available on the current FIX/FAST channels:

These products will be available with the new tag 207 value XNYM for customer testing in New Release on Monday, June 18. The production launch date will be announced in the CME Globex Notices as soon as it is available.

CME Globex Performance Release

New information is now available in the Client Impact Assessment on the move to single IP for iLink sessions in the production and disaster recovery environments. Information on the iLink launch date for the Disaster Recovery environment on November 4, 2012, is also available.

CME Group is implementing iLink and FIX/FAST infrastructure upgrades to the CME Globex electronic trading platform that will result in reduced message response times and faster market data messaging. This release is expected to significantly reduce iLink round trip times and improve FIX/FAST performance. As a result, bandwidth utilization is expected to increase by 10-20%.

This release also features iLink messaging changes. Detailed information on this launch, including impacts and launch schedules, is available in the Client Impact Assessment.

The FIX/FAST launch will be phased in over 5 weekends, August 26 through October 7, during which the source IPs for each channel will change. The iLink launch will feature an Early Adopter period, October 7 through October 12, and a production launch Sunday, October 14. All iLink sessions must migrate to new IPs and ports in order to access the new high performance production environment.

Customers who wish to participate during the Early Adopter phase must select the sessions that will be migrated and inform their Global Account Manager no later than Wednesday, October 3. Please note: To minimize the risk of business interruptions, CME Group strongly recommends that customers participating during the early adopter phase direct no more than 20% of their sessions to the new IPs and ports.

Customer certification is not required, but CME Group strongly recommends all system providers test these changes thoroughly in New Release. Good 'Till Cancelled and Good 'Till Date (GTC/GTD) orders will not be impacted.

Please contact your Global Account Manager with any questions or concerns at 312 634 8700, in Europe at 44 203 379 3754, or in Asia at 65 6593 5574 for additional information.
